I've solved the problem, i've restructured code (I've deleted almost all globals variables) and i've added '-lc -lm -lc' flags to makefile. I suppose the problem was the code structure, too many global variables due to bad adaptation from an arduino code style (All source files are pasted into in the same file) I put the makefile here, I hope it is useful to someone.
I've been working on this problem for the past few hours, and finally solved it. For me it had to do with the fact that the avr libm. A must be included in the linker command, and I was using the Math.
H library, which is separate from the libc. A library, and wasn't being linked correctly.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
